NetEase Games has announced a ban on keyboard and mouse adapters for Marvel Rivals on PlayStation 5 and Xbox Series consoles. The company cites unfair advantages gained from increased control sensitivity and aiming assistance as the reason for this policy violation. Adapters such as XIM, Cronus Zen, Titan Two, KeyMander, and Brook Sniper, which simulate gamepad input from keyboard and mouse controls, are specifically targeted. This is particularly problematic in competitive modes, especially when auto-targeting is enabled. NetEase's statement clarifies that any device or program emulating gamepad control via keyboard and mouse is considered a violation, creating an uneven playing field. The company has implemented detection tools to identify adapter usage with high accuracy, resulting in account bans for offenders.

Separately, a correlation has been observed between higher FPS and increased ping in Marvel Rivals. While the effect might be negligible with low ping, a jump from, say, 90ms to 150ms can severely impact gameplay. This issue appears linked to frame rate. Currently, the recommended solution is to wait for a game patch and experiment to find the optimal FPS/ping ratio. Some players suggest maintaining an FPS around 90 as a temporary workaround, though this might seem unusually low to players accustomed to higher frame rates in other games like Counter-Strike 2.
